Technical Details

The P55 is Ideal for:

· Flight testing

·Vehicle testing

·Hydraulic systems

·Product - Process control testing

The compact, robust P55 provides cost-effective reliability for severe test environments.

With extreme resistance to shock and vibration, the compact P55 delivers the same high-level performance expected from more delicate differential pressure transducers.

In fact, the P55 withstands shock and vibration that can damage or even destroy other differential pressure transmitters in its class. With variable reluctance sensing technology, the P55 delivers fast dynamic response, high resistance to vibration and superior signal stability through ambient temperature change for a wide variety of low-pressure measurements. The P55 will accept both liquids and gases directly at the sensing diaphragm - and there are no internal isolation fluids to slow the sensor response or cause excessive temperature drift errors.

The lightweight, compact unit measures just 1.5" x 1.5" x 4.5" and includes four mounting holes so that it can be easily secured to any flat surface.


·Wide pressure measuring capability: ±2.22" H20 to 3200 psi in 23 full-scale ranges

·Wet-Wet capability: accepts liquids & gases on both sides of the diaphragm

·Withstands shock and vibration

·Compact size: just 1.5" x 1.5" x 4.5"

·Easy to mount with attached mounting flanges

·Excellent temperature compensation characteristics

·CE approved version available

·Available in differential and absolute versions

The P55 is available in three output configurations:

·4-20 mA output
A true two-wire system which will operate over a supply voltage of 9 to 55 Vdc.

·DC output
Provides a ± 5 Vdc signal.

·Isolated DC output
Provides a ± 5 Vdc signal, isolated from the power supply by 100 MOhms.

An absolute pressure version with a welded variable reluctance sensor is also provided. Zero and span controls are available for external adjustment. Selection of connector or pigtail wiring options. 

Now available in 316 SS for sea water and saline solutions and Inconel for brine and other corrosive media and Hastelloy.
